3.6.2 Equipment Maintenance and Decontamination Field equipment will be maintained per each manufacturer's recommended maintenance schedule. Any field equipment that comes into contact with sample media will be decontaminated per the methods described in Section 3.3. 3.6.3 Field Monitoring Measurements Each soil sample interval is monitored in the field for possible total volatiles by use of a portable hydrocarbon field analyzer.A portion of the sample interval adjacent to the retained sample is placed in a sealable air-tight plastic bag. After the bag has been sealed for a minimum of five minutes, the sample is measured and the meter readings recorded. The field analyzer is a battery-powered instrument which detects and indicates concentrations of total volatiles(gas or vapor) in the air in the parts per million (ppm) range. Samples are drawn continuously by means of a built-in pump and analyzed. The instrument will respond to numerous hydrocarbons including petroleum products. Results of the analysis are reported in ppm and are used only as a qualitative field measure of potential soil contamination. The photo ionization meter (PID) that will be used is a RAI systems MiniRAI Plus Professional PID with a 10.6eV lamp. Readings will also be obtained in the breathing zone during sampling and recorded. The HASP details air monitoring. 4.0 RECORD KEEPING 4.1 Chain of Custody Form Samples will be collected,transported, and received under the chain-of-custody protocols consistent with procedures established by the EPA for litigation-related materials. Each transfer of possession will be logged on the chain-of-custody form. Signature of relinquisher and recipient will be required. A copy of the chain-of-custody form will be produced and filed by GRI whenever samples will be sent to the laboratory. Upon receipt at the laboratory, the laboratory custody procedure will provide the mechanism through which the disposition and custody of the samples will be accurately documented during each phase of the analytical process. A sample receipt checklist will be used to document the condition of samples on arrival at the laboratory. 4.2 Field Notes,Photograph Log Field notes will be recorded in a log book. The log book will also contain a record of photographs taken during field activities. 5.0 PROJECT SCHEDULE The following table provides a feasible schedule for performing the tasks identified in this workplan. Completion dates(days following an activity or actual date)for each task are identified. 1163-3 2014 0617 PEAWP 3 12 GPJ
